Thanks Praveen.do i have to solder the usb port provided with GR sakura & connect usb modem to it.any additional driver required or serial.begin() will do.
the usb type a and mini usb connectors are shorted inside the board..according to my knowledge u cant use the host (or function) feature and the virtual com port simultaneously...plz do correct me if i am wrong..
Yes, you are right, but you can create a virtual com port with another program and access it. I use virtual com port driver (www.virtual-serial-port.org/ ) in this case.
